On the map which symbol represents a cold front? choose the correct letter.

The correct answer is D.

A cold front is a band of instability that occurs when a mass of cold air approaches a hot air mass. The cold air, being more dense, generates a "wedge" and gets under warm and less dense air.

Cold fronts move quickly. They are strong and can cause atmospheric disturbances such as thunderstorms, squalls, tornadoes, strong winds and short snowstorms before the cold front passes, accompanied by dry conditions as the front advances. Depending on the time of year and its geographical location, cold fronts can come in a succession of 5 to 7 days.

In weather maps, cold fronts are marked with the symbol of a blue line of triangles that indicate the direction of their movement, like the one in option D.

according to the quotation from booker t. washington's 1895 atlanta compromise speech.

in the great leap from slavery to freedom . . the masses of us are to live by the production of our hands . . we shall prosper . . as we learn to dignify and glorify common labor.

washington believed that  hard work had its own kind of dignity.
